The fearsome Peregrine Falcon feeds on smaller birds, including pigeons, gulls, sparrows, swallows and starlings. Falcons are found worldwide and attack with terrifying dives at speeds up to 200 MPH, tearing into the victim bird with lethal sharp beak and talons. High-visibility scare strikes instant terror. Predator birds create a hostile and dangerous environment for any bird, making them much less likely to approach an area or congregate. Remove nests first.
